Plain-English summary
Does failing to plead an affirmative defense waive it, or can it be used at summary judgment?
The Court will decide whether a defendant who omitted an affirmative defense from its answer can still rely on that defense later as the basis for a summary judgment motion. The case asks how strictly Rule 8(c)(1)’s "must plead" requirement should be enforced.
Why this matters
The decision will affect how strictly federal courts enforce pleading rules and how parties conduct litigation. If courts treat failure to plead an affirmative defense as a forfeiture, defendants may lose defenses they intended to raise. If courts allow such defenses at summary judgment, plaintiffs may face surprise defenses late in the case. The ruling will shape litigation strategy, case management, and the balance between procedural formalities and resolving claims on their merits.
